Something went wrong with r211426, it is an older version of this code
and should not have been committed. It was reverted with r211434.
Original commit message:
We didn't properly implement support for the sized integer suffixes.
Suffixes like i16 were essentially ignored instead of mapping them to
the appropriately sized integer type.
This fixes PR20008.

The compilation pipeline doesn't actually need to know about the high-level
concept of diagnostic mappings, and hiding the final computed level presents
several simplifications and other potential benefits.
The only exceptions are opportunistic checks to see whether expensive code
paths can be avoided for diagnostics that are guaranteed to be ignored at a
certain SourceLocation.
This commit formalizes that invariant by introducing and using
DiagnosticsEngine::isIgnored() in place of individual level checks throughout
lex, parse and sema.

Summary:
'sizeof' is a UnaryExprOrTypeTrait, and it can contain either a type or
an expression. This change threads a RecoveryTSI parameter through the
layers between TransformUnaryExprOrTypeTrait the point at which we look
up the type. If lookup finds a single type result after instantiation,
we now build TypeSourceInfo for it just like a normal transformation
would.
This fixes the last error in the hello world ATL app that I've been
working with, and it now links and runs with clang. Please try it and
file bugs!

We currently allow unqualified lookup for instance methods but not
static methods because we can't recover with a semantic 'this->'
insertion.
ATL headers have static methods that do unqualified lookup into
dependent base classes. The pattern looks like:
template <typename T> struct Foo : T {
static int *getBarFromT() { return Bar; }
};
Now we recover as if the user had written:
template <typename T> struct Foo : T {
static int *getBarFromT() { return Foo::Bar; }
};
... which will eventually look up Bar in T at instantiation time.
Now we emit a diagnostic in both cases, and delay lookup in other
contexts where 'this' is available and refers to a class with dependent
bases.

While matching a non-type template argument against a known template
type parameter we now modify the AST's TemplateArgumentLoc to assume the
user wrote typename. Under -fms-compatibility, we downgrade our
diagnostic from an error to an extwarn.

This implements the central part of support for dllimport/dllexport on
classes: allowing the attribute on class declarations, inheriting it
to class members, and forcing emission of exported members. It's based
on Nico Rieck's patch from http://reviews.llvm.org/D1099.
This patch doesn't propagate dllexport to bases that are template
specializations, which is an interesting problem. It also doesn't
look at the rules when redeclaring classes with different attributes,
I'd like to do that separately.

caused us to perform copy-initialization for the parameters of an allocation
function called by a new-expression multiple times, resulting in us rejecting
allocations that passed non-copyable parameters (and much worse things in
MSVC compat mode, where we potentially called this function multiple times).

This lets us diagnose and perform more complete semantic analysis when faced
with errors in the function body or declaration.
By recovering here we provide more consistent diagnostics, particularly during

I've suggested removing it to -core and disabled this diagnostic by default.

Summary:
Previously, we would generate a single name for all reference
temporaries and allow LLVM to rename them for us. Instead, number the
reference temporaries as we build them in Sema.
